The motivation of this paper is to provide an overview of the most recent trends and of the
future research directions in color image and video processing. Rather than covering all …

This paper presents a novel watermarking approach for copyright protection of color images
based on the wavelet transformation. We consider the problem of logo watermarking and …

In this paper, we present a robust hybrid watermarking method applied to color images for
authentication, which presents robustness against several distortions. Due to the different …

Compared with other existing methods, the feature point-based image watermarking
schemes can resist to global geometric attacks and local geometric attacks, especially …

A novel, efficient and robust watermarking scheme for protection of document image
contents is proposed in this work. An integer wavelet-based watermarking scheme for …

The rapid development of the internet allows digital media being easily delivered, copied
and even tampered. The watermarking issue has thus focused mainly on the medium of …

This paper identifies a novel digital watermarking approach for copyright protection and
authentication of medical images based on the wavelet transformation. We consider the …

We propose a new approach to commutative watermarking-encryption (CWE). A
permutation cipher is used to encrypt the multimedia data, which leaves the global statistics …

In this paper we examine some problems related to capturing the structure and the topic
name space of learning content in the context of topic map authoring. We demonstrate that …

This article provides a review of the state of the art in watermarking techniques specifically
designed for color images. It presents an overview of the color image watermarking methods …
